const classafBedSheet::FileAsset

sys::Obj
  afBedSheet::FileAsset

A wrapper around a File object used to prevent excessive polling of the file system. As every call to File.exists() typically takes at least 8ms-12ms, this is probably a good thing!

FileAssets are acquired from FileHander and should be used to embed client URLs in your web pages.

clientUrl

Source

const Uri? clientUrl

The URL that clients should use to access the file resource. The clientUrl contains any extra WebMod path segments required to reach the BedSheet WebMod. It also contains path segments as provided by any asset caching strategies, such as Cold Feet.

Client URLs are designed to be used / embedded in your HTML.

Returns null if file doesn't exist

etag

const Str? etag

The ETag uniquely identifies the file and its version. The default implementation is a hash of the modified time and the file size.

Returns null if file doesn't exist

Returns true if the file exists. (Or did at the time this class was created.)

localUrl

Source

const Uri? localUrl

The URL relative to the BedSheet WebMod that corresponds to the file resource. This may be the same as clientUrl or it may not. If in doubt, use the clientUrl instead.
